STORAGE BATTERY.

Application filed March 24, 1919.

T o all 1li/:omit may concern Be it known that I, Amnou J. Baumann, a citizen of the United States, residing at Chicago, in the county of Cook and State ot' Illinois, have invented new and useful lmprovements in Storage Batteries, ot' which the following is a specification.

This invention relates to storage batteries, and more particularly to the supporting means of the battery plates. the invention having for its object to provide a very simple and highly etlicient means engagcable with the ends of the plates and constructed to securely hold the same properly spaced in the battery jar or container.

The object stated is attained by means ot a novel combination and arraugcnwnt of parts to be hereinafter described and claimed, and in order that the same may be better understood, reference is had to the 'accompanying drawing. forming a part of this specification.

In the drawing,

Figure l is a horizontal section showing;f the application of the invention;

Figa-2 is a perspective view ot' one of the supporting devices. and Fig. il is an eleva tion of a fragment ot' one of the supporting devices.

Refcrrin; r specifically to the drawing, l0 denotes the outer jar or container of the battery in which the usual plates Il are mounted. At opposite ends of the container are positioned supports for the ends of the lates. 'lhese supports comprise plates l2 of lmrdArubber. celluloid or other material impervious to the electrolyte. and they are plain on one side to snugly fit the end walls of the jar, whereas their opposite sides or outer faces are made with parallel, and spaced vertical grooves 13. The grooves of the respective supporting' plates face each other and they are'also in alinement. lt will therefore be seen that if the battery plates ll are inserted between the plates 12 so that each one of the former seats at its ends in opposite grooves lil. all the battery plates will be securely supported and held in proper laterally spaced relation. This arrangement is clearly illustrated m Flg. l. lt will be noted that the supporting plates l2 seat snugly between the opposite side Specification of Letters Patent.

walls of the container 10. and as they alsoA i seat against the end walls, and are held against inward displacement when the battery plates are in place, the latter are se'- curely supported even ar'ter the insulation used therebetween has disintegrated.

The supporting plates 12 will also absolutely prevent the possibility of short circuits duc to buckling; of the battery plates caused by heavy discharges. and each battery plate is rigidly held in place and is allowed to perform its natural functions as loner as there is any active material left in the grids.

The supporting plates l2 also facilitate repairs as they are not permanently fastened in the container ll), but are removable, this enabling the repairinan to remove the element from the cell in one complete unit without soaking or heating the c'ontainer.

The plates 12 have perforations 14 as shown in Fig. 3 to provide for circulation of the electrolyte, thereby reducing to a minimum any heat which might be developefl by crowding the cell.

The plates l2 also insures the manufacturer against dama e from careless workmanship in assemb ing the cells, as each clement must be fitted into the plates, and there is only one way they can be fitted, and that being the simplest way. The invention therefore results 1n a uniformity of construction which is greatly desired in storage battery production.

I claim:

1. In a storage battery, means for supporting the plates in spaced relation, said means comprising members havin spaced parallel grooves in which the en s of the plates seat, said grooved portions having perforations.

2. ln a storage battery. means for snp portingr the plates in spaced relation. sind means comprising plates removably seatin against the end walls of the container an between the side walls thereof. andghaving spaced parallel'grooves in their outer faces in which the ends of the battery plates seat, said groovcd portions having perfolations.

ln testimony whcrcot` l atiix my si nature.
